2020 CHEVROLET TRAVERSE Complaints

2020 Chevrolet Traverse vehicles may experience a loud, rumbling exhaust leak caused by a failing front exhaust pipe bracket weld, frequently noted in complaints. While special coverage exists for other model years, 2020 owners are experiencing similar issues, with some reports suggesting it may not be covered under the same official, extended recall. My vehicle is experiencing the same issues that the 2019, 2021, and 2022 model are experiencing why is my 2020 and other owners of a 2020 year skipped to be covered for this identical problem.

Failed/failing hydraulic timing chain tensionors. Common issue for this engine said to be caused by poor oiling. After speaking to many shops, this is just one of the many, very common issues that occurs in this vehicle. Started on February 20th, 2026. There are no warning or check engine lights on for this issue. People who are unfamiliar with the symptoms may be driving a vehicle that may suddenly stop running without warning as there is no light illuminated on the dash. Online it states that this may be caused by not performing oil change services on time. For my particular situation, I am a preventative maintenance specialist for the past ten years. I am professionally trained and perform PM services daily. I know my Traverse has been very well maintained and serviced with premium synthetic motor oil since my ownership. And despite this, I am now having to pay a significant amount of money to have this fixed or risk the safety of myself, my family and really anyone else on the road. My vehicle is available upon request any time.

Front exhaust bracket weld failed creating a hole in the exhaust system, as covered by GM Bulletin PIP5681C. This resulted in a loud noise as well as exhaust leaking into the cabin since it is near the engine, right above the drivers center console

My seat belts do not click when fastened or stay fastened. Sometimes I have to try several times to get the seabelt to click.

Vehicle: 2020 Chevrolet Traverse VIN: [XXX] Mileage: 50,100 miles Ownership: Original owner The driver’s seat belt intermittently fails to latch. This is a primary safety restraint system, federally required, and critical for occupant protection. The failure occurs randomly and cannot be reliably duplicated. The dealer inspected the seat belt buckle and confirmed no debris or obstruction. The dealer was unable to duplicate the issue during their inspection. Video documentation from the owner of the intermittent failure is available. This appears to be a premature mechanical failure of a safety-critical component. The vehicle is only 50,100 miles and properly maintained. Failure of the driver’s seat belt could prevent proper restraint in an accident, creating a serious safety risk. There are no open recalls related to this issue, and the vehicle is out of warranty. I contacted the manufacturer about goodwill assistance for repair. They confirmed that, since there are no open recalls, the issue cannot be duplicated, and the vehicle is out of warranty, they will not provide reimbursement or cost assistance. The driver’s seat belt should not fail during the expected life of the vehicle. At 50,100 miles on a 2020 Traverse, this appears to be a premature mechanical failure of a safety-critical component. I am submitting this complaint to document this issue for this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Cracked flex pipe. Common issue with all traverse models/years. Needs to be addressed and recalled!

The forward exhaust bracket weld broke causing a rattling noise and allowing exhaust fumes into the car which is incredibly dangerous.

Vehicle is current at 101,102 Miles, however, the issue started to occur at 75,350 miles. It is the common issue crack in the exhaust pipe just before the flex exhaust tube due to poor welding of the bracket causing the exhaust system to rattle and leak exhaust into the cabin. The same issue has been addressed under Special Coverage N222385510 for 2021 vehicles, and another one was issued for 2019 Chevrolet Traverse and Buick Enclave vehicles. GM Bulletin PIP5681C describes the issue in detail and acknowledges that the same process was used on their 2018-2022 vehicles, but they are only covering the repair of the 2019s and 2021 vehicles. Exhaust fumes do reach inside the cabin of the vehicle especially on calm mornings that have no breeze. This is a potential carbon monoxide hazard. The is no scrape marks or damage to the undercarriage that would have caused the issue, only the heating and cooling of the exhaust system.
